I'm an intern at Systra in railway engineering. I'm working on BIM technologies, such as railML, and we are making a study to use this format in the future, that's why I have so many questions to ask you.

Does someone have an example of a clothoid represented with its geometry? For example:

Indeed, the example you provided only states that you have a clothoid,
but not which specific type. Please use one of the other available
enumeration values:
* TS_cubicParabola
* TS_parabola4
* TS_WienerBogen
* TS_BlossBogen
* TS_Sinusoide
* TS_Cosinusoide
You can also define your own value (if correct one is missing) making
use of the any enumeration value.

To be clear: railML does not model the transition curve parameters.
Please look them up in a corresponding reference or try to include the
LandXML schema.
